Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121248, here are decompositions:
- 19 + 121229 = 121248
- 59 + 121189 = 121248
- 67 + 121181 = 121248
- 79 + 121169 = 121248
- 97 + 121151 = 121248
- 109 + 121139 = 121248
- 167 + 121081 = 121248
- 181 + 121067 = 121248
Showing the first eight; more decompositions exist.
